Detection of Sugar by Ion Chromatography


The working principle of ion chromatography is to use the dissociability of the analyte to interact with the charged functional groups on the surface of the stationary phase, so that the analyte is retained. With the gradual discovery of the role of carbohydrate compounds in the field of medicine, the analysis of carbohydrate compounds has attracted more and more attention from scholars. Alfa Chemistry uses ion chromatography to analyze your carbohydrates efficiently and accurately.

Detection of Sugar by ion chromatography


Saccharides are widely found in nature, and their types include monosaccharides, oligosaccharides, polysaccharides, acid sugars, amino sugars, sugar alcohols, and their isomers. Carbohydrate compounds are widely found in food, beverages and Chinese herbal medicine. In recent years, people have gradually discovered the pharmacological effects of carbohydrate compounds. For example, glucosamine compounds are widely used in the preparation of anti-osteoarthritis drugs, immune-enhancing health foods, antibiotic synergists, and synthetic antibacterial drugs. The early analysis of carbohydrates mainly used the specific optical rotation of their aqueous solutions to determine their purity. With the advancement of science and technology, electrophoresis, photometry, volumetric analysis, etc. were invented. However, these methods have poor selectivity and cannot separate the sugars in the system, and the results obtained are the analysis results of the total sugars. Subsequently, methods such as gas chromatography and capillary electrophoresis were developed. However, these methods have disadvantages such as complicated operation steps and poor stability. In addition, due to the high boiling point, low volatility, and difficulty of gasification of sugar compounds, they must undergo a derivatization reaction before they can be transformed into volatile and thermally stable substances for determination. This also brings more practical analysis to the work. Great inconvenience and error. We are currently using a more advanced ion chromatography method. Ion chromatography can meet the requirements of fast, simple, efficient and sensitive detection.
